Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Hello Robert,
I am using MacOS Mojave 10.14.6.
vna_qt.app works fine, you should see the USB device /dev/cu.usbmodemDEMO1
See attached menu Device: vna_qt_Device-menu.png

It did work for one time. It fails thereafter.

Tried the nanovna-saver with the same issue.

Is there a way to reset the software to factory, without a USB?
